TransformVlcBitmap: Why we need to convert the bitmap from 160x480 to 240x320 #81

In the file FrameRenderer.cpp. What is the function TransformVlcBitmap() going to do?

I believe the image stream from the VisibleLight cameras is 160x480.

However it the function TransformVlcBitmap() it tries to store such 160x480 bitmap into a 240x320.

Why we need to do this?

My guess from several raw pictures that I took, is that in 160x480 the image is stretched. Meanwhile with 240x320, the image is at its correct scale. Though, I am not completely sure about this. I am also looking for a proper specification and details regarding the environment understanding sensor camera.

Right. Literally, there are not many official documentations for HoloLens research mode...
